toward
the
FAST

increases
engine speed; mov-
ing it
back ward
toward the

Forward Speed Control (FSC)
Forward Speed Control (FSC) has two functions:
One is to set forward travel speed, and the other is
to establish the
NEUTRAL-PARK
position. When
the FSC lever is moved into the
FORWARD
posi
-
tion, a friction lock holds any forward speed setting
from 0 to 10 mph (0 to 16 km/h). The ground
speed is pro portional to the lever position; the
further the lever is advanced forward, the faster the
tractor moves. It is not necessary to hold the FSC
in position since the friction lock maintains the
selected lever position. Pulling back on the steer-
ing levers overrides the FSC setting and slows or
stops forward travel. Releasing the steering levers
allows the tractor to resume forward travel at the
speed set by the FSC lever. To stop and park the
machine, the FSC lever is moved backward to the
NEUTRAL-PARK
position.
Steering Levers
Each drive wheel is controlled by its own indepen-
dent steering lever, for both steering function and
FORWARD/REVERSE
motion. The FSC lever
sets the maximum forward speed, and also sets
the for ward position of the steering levers. The
steering levers operate
only with a backward
pulling
move ment of the lever, which causes the
drive wheel for that lever to first slow down, stop,
and then reverse with a full backward lever stroke.
The levers are released to the
FORWARD
position
for “straight-ahead” ground travel.
NOTE:
Pushing forward on the steering levers will
not cause
any
change in tractor motion - there will
be no steering lever reaction and there will be no
machine damage.
Blade Clutch (PTO)
The blade clutch lever is located on the right side
of the seat behind the right fender and is used to
engage and disengage the mower blades. The
blade clutch lever has two positions. Pushing the
lever
DOWN engages
the PTO that drives the
mower blades. Pulling the lever
UP disengages
the PTO and engages the blade brake.
